Abstract:

With the support of cloud computing technology, the age of big data is full of opportunities and challenges. In order to fully understand the big data environment, we use visual analysis tools Bibexecl and CiteSpaceIII to conduct visual analysis of knowledge map on big data research in the past decade. Based on background knowledge of big data, we demonstrate the distribution and knowledge base of literature, and identify the international dynamic, academic frontiers and development path of big data. In the end, we put forward conclusions and recommendations. The age of big data requires collaboration of interdisciplinary and cross-regional forces. Meanwhile, the issue of privacy should arouse due concern. Big data promotes education reforms and the establishment of data sharing alliance.
